Has anyone ever heard of this setup? I love my 400ex frame and the suspension on it, and don't want to get rid of it.

I personally like the ride better than a 450R....
Maybe it was a Honda 450F engine, I know one of them dropped in and fit perfect, someone told me they read it in Dirt Wheels magazine....
Anyone else heard of this....:devil:

Check in the thread.Someone posted a name for a company that does the conversion.I am in the middle of putting a yz426 motor into a 400ex chassis to race TT.Should handle great and be fast

JB racing does it too.
Your looking at least $1500+ the cost of the motor ,carb and electronics.
With the yzf conversion you need to fab up oil tank mounts and /or a custom oil tank, so that will add to your cost more.

You havent rode a 250r enough. :p
The crf\ex conversion rides better than a regular 400, its amazing what a 30 pound weight reduction will do.

i've never ridden a 250R...I only wish I had one....
I am going to race the 400 as it sits now, and then I will probably do it next winter...
